We’re here to build for the long term.⚫️

One week on Arc Mainnet.

624M USDC in circulation.
$6.8B USDC transferred.

Day one was just the beginning.

[Chris Ries @chrisries]

For any teams building on @arc or otherwise: you should really consider applying. I'm happy to review your application and give you a referral.

Just send me a DM. It could change your life.

[Arcals @arcals_circle]

Your mint is already complete, and the Arcal is safe in your wallet.

For batch mints, content registration is currently completed one Arcal at a time. If you don’t register, nothing is lost and there is no deadline—the Arcal simply remains Content Pending, its 360 π digits remain unregistered, and it cannot be converted into 360 ARCL until registration is completed.

You do not need to mint again or pay another 0.1 USDC. Only the registration transaction remains.

[Arcals @arcals_circle]

Slowly but surely.

More updates on the way. $ARCL

[Arcals @arcals_circle]

Watch what happens when that reach meets Arc.

A larger circle is forming.⚫️

[Circle @circle]

Circle 🤝 @binance

Circle and Binance are continuing to build together through a new five-year commercial agreement to expand USDC access across emerging markets.

Binance has also made a $100M strategic investment in Circle.

@chrisries Very curious to see how Arc approaches post-quantum account migration without breaking EVM compatibility.

[Arcals @arcals_circle]

Fair questions. We won’t answer them with “soon.”

1/ FORM ↔ FLOW conversion opens when the inscription phase closes. The ratio remains fixed: 1 Arcal ↔ 360 ARCL.

The target is the complete 1,000,000-Arcal sequence—but this is not an endless mint. If inscriptions reach a sustained, verifiable stall, we will activate a publicly announced early-close procedure:
— end further inscriptions;
— permanently retire the remaining issuance;
— burn the corresponding unallocated ARCL;
— finalize the actual supply;
— open conversion.

2/ ARCL will trade on Arc against native USDC. The venue, pool structure, contracts and activation block will be published before trading opens.

3/ ARCL is the protocol asset for the Arcals marketplace and permissionless launchpad. Protocol revenue will support transparent ARCL buybacks and liquidity.
Inscription is Phase I.

Conversion and the market are Phase II.

The launchpad follows.

The circle will close—through completion or through a transparent finalization process.

⚫️ HOW TO INSCRIBE AN ARCAL

There are two ways to inscribe: with an AI Agent or directly from a browser wallet.

We recommend the Agent path—faster, built for continuous inscription, and powered by @circle Agent Wallet with sponsored gas.

Here is how to begin.

[Arcals @arcals_circle]

Welcome, Arcalers.
Every @arc makes a @circle .⚫️

[Arcals @arcals_circle]

@n5hjb @circle After a successful inscription, you receive a numbered Arcal—not ARCL directly. Each Arcal corresponds to 360 ARCL.

Conversion is not live yet. The opening time will be announced later. Once enabled, you can ask your agent to convert it or use the official website.

[Arcals @arcals_circle]

@Star_club88 @circle Your mint was successful. The “+0 Arcals” display is only a MetaMask ERC-721 display issue.

[Arcals @arcals_circle]

@n5hjb @circle We hear you. Please be patient.

the community will shape what comes next, and we’ll continue improving the experience.

[Arcals @arcals_circle]

Your mint was successful — Arcal #2301 is confirmed onchain and owned by your wallet. The “+0 Arcals” display is only a MetaMask ERC-721 display issue.

We’ve updated the browser flow to proceed automatically into content registration after Mint. For this earlier inscription, reconnect the same wallet on https://t.co/JTbaC1Fqqd, search #2301 in Explore, and select Retry registration. No additional 0.1 USDC is charged—only standard network gas.

[Arcals @arcals_circle]

This can be recovered through your Agent. Send it:

“Recover my interrupted Arcals inscription for request ID 7df8203a-5013-45de-aa79-e3d5fff054d5. Use the original wallet and ledger, run the official status recovery flow, and do not submit a replacement Mint or use a new idempotency key. Resume the remaining batch only after the original request reaches a confirmed final state.”

[Arcals @arcals_circle]

Every Arcal contains:

— 360 consecutive digits of π
— an exact position in the sequence
— 360 $ARCL mapped to it

Every 0.1 USDC inscription payment forms part of the initial liquidity.

Every arc makes a circle.

2/ With a browser wallet

Go to https://t.co/bNmS61XMsW

Connect MetaMask or another EVM wallet. Start an inscription and keep the page open while the work runs locally.

Once completed, confirm 0.1 Native USDC to receive the next numbered Arcal.
